Hi,<br>
maybe this is similar to the ipoib issue discussed here around march
this year.<br>
"IPoIB on CentOS 6.5".<br>
<br>
In the recent RHEL 6 Version it was fixed.<br>
<span class="term">BZ#<a
href="https://bugzilla.redhat.com/show_bug.cgi?id=1187666">1187666</a></span>
solved it for our site.<br>
Hope ther newest Redhat/CentOS 6.7 kernel is not faulty again.<br>
<br>
Which kernel version you are using?<br>
<br>
<br>
best regards<br>
M.Soysal<br>

<p class="MsoNormal">Not sure if this is where I can get help
with this, but...<br>
<br>
Running standard CentOS 6.7<br>
Mellanox infiniband adapters<br>
Running OpenSM on one node<br>
<br>
If that node reboots, suddenly it can no longer ping/be pinged
across the ipoib network.<br>
It can ping itself and it can ping any boxes that get
rebooted.<br>
Until they are rebooted, those boxes can ping each other but
NOT any node that has been rebooted.<br>
<br>
Almost like there is a new network and you have to reboot to
join it...<br>
<br>
Grrr...<br>
ibhosts still shows all hosts. I can also ibping any node just
fine. It is just the IPOIB bit that seems to choke.<o:p></o:p></p>
